Areas with higher rates of gun ownership have higher rates of suicide

ANNAPOLIS, Md. — People who live in areas with higher rates of gun ownership are more likely to commit suicide, whether by gun or by some other means, say researchers who study the effects of firearms on society.

The correlation between gun ownership and suicide rates takes on added significance given the increase in firearms sales in the wake of tragedies like the mass shooting at Sandy Hook Elementary in Connecticut. This week, a University of Maryland graduate student who suffered from mental illness, shot two of his roommates with a legally purchased 9 millimeter handgun, killing one before turning the gun on himself.

“Firearms suicides tend to be very compulsive acts,” said Professor Daniel Webster, director of the Johns Hopkins Center for Gun Policy and Research. The compulsive nature of the act could be one of the factors in explaining why areas with more firearms have higher suicide rates. Webster recently testified in support of one of Maryland Gov. Martin O’Malley’s proposed gun control bills.

There appears to be consensus amongst most researchers that there is a direct correlation between gun ownership and suicide rates. Guns are the No. 1 way people kill themselves in the U.S. The lethality of firearms, which are far more effective than alternative suicide methods like hanging or overdose, combined with the sudden, overwhelming impulse to do self-harm creates a deadly mix, experts say.

“(A gun) is immediate. It’s easy, it’s right there,” said Linda Hofmann, director of Behavioral Health Services at Frederick Memorial Healthcare System. “It doesn’t require planning if they have a firearm in the house.”

“Certain individuals may find suicide with a gun more appealing than alternative methods — perhaps because of speed, the high probability of success, or because it is a culturally accepted method — and thus only attempt suicide when a gun is available,” said a 2002 study conducted by Mark Duggan, a professor of health care management and public policy at the Wharton School at the University of Pennsylvania.

And it isn’t just households with guns that are more at risk for suicide, all of their neighbors have a higher likelihood of taking their own lives as well, studies say.

Duggan’s study suggests that people without easy access to guns don’t simply find another method to commit suicide, or may not be as successful. Without guns around, suicide rates go down.

Restricting access to firearms, especially by the mentally ill, can “significantly reduce suicides,” said Webster, of Johns Hopkins.

In 2006, the Israeli Defense Forces, in response to an increase in suicides, restricted troops from bringing home service weapons on the weekends. By 2010, suicides by Israeli soldiers had decreased by 40 percent, according to a study by IDF psychiatrists.

When Washington passed a law banning the possession of handguns in the city, Duggan’s study concluded “that gun suicides occurring in the D.C. metro area declined by 23 percent.”

A 2001 survey by the Centers for Disease Control and Prevention found that in the 15 states with the highest levels of gun ownership there were nearly 15,000 total suicides, compared with more than 8,000 total suicides in the 15 states with the lowest gun ownership, despite the latter having a larger population.

Wyoming and Alaska ranked highest in gun ownership, according to a survey conducted by the CDC, with more than half of households owning a firearm. Hawaii and New Jersey reported the lowest rate of gun ownership, with fewer than 13 percent of respondents claiming to own a gun.
